The First World War was both an historical and a philosophical event. Philosophers engaged in what Kurt Flasch aptly called "the spiritual mobilization" of philosophy. Max Scheler was particularly important among these "war philosophers", given that he was the one who penned some of the most influential philosophical writings of the First World War, among them Der Genius des Krieges und der Deutsche Krieg. As I aim to show, Max Scheler's war writings were crucial for Jan Patočka's interpretation of the (...) First World War in the sixth of his Heretical Essays. However, the importance of Scheler's war writings goes far beyond the First World War for Patočka, since they offer Patočka a far-reaching interpretation of the 'excessive' character of the 20 th century. As I will show through the example of Max Scheler, the German war philosophers succumbed to a dangerously romantic conception of "force" – and it is this ominous force, which Patočka takes to lie at the root of the increasingly excessive character of the 20 th and 21 st centuries.
